The location of the valve seat or hydro-carbon inlet above the airinlet 34 and the foraminous support 26 between them the fluid flowingtherein will be evaporated While the air passing. therethrough will besubdivided into numerous small currents which will cause it to becomethoroughly 4 mixed with the hydro-carbon gas. "While I have describedthe device as employin a fluid-hydro-carbon it will be understood t at*it may be usedV equally Well for combining an explosive mixture of gasand .air 'when the former Vis introduced directly in a gaseous. statethrough theinlet 24. i

A carbureter embodyin my invention is simple in construction .an reuires but few parte, the arrangement of Whic is such that y anadjustment of the air inlet passa e the quantity of hydro-carbon whichshoul to the engine Acylinder is tionately.

I claim as my invention:

1 In a carbureter, the combination with a pass regulated propor- Icaslng having air 'inlet and 'outlet passages and a hydro-carb on inlethaving a valve seat, of an oscillatory member for adjusting the airinlet passage, avalve head carried thereon and coperatmg with the valveseatV and means for causinga longitudinal movement of the memberrelatively tothe casing during its oscillatory movement to' control thedischarge area of thehydro-carbon passage.

2. In a carbnreter, the oombination'with a casing comprising a mixingchamber and a hydro-carbon reservoir located beneath and Y essaies Pug 1Amovement of the at one side of the chamber and having a pas- Sageleading Int() the JQgervgjr hgggglglg he chamber and a valve seat insaidpassage, of ari-arm located'at the betteln voir and chamber, a ioatconnected to the one end of the arm, and a. valvehead supported on thelatter and coperating with .the seat in the inlet passage. v A

3. In a carbureter, the combination withV a casing comprising a mixing'chamber and a hydro-carbon reservoir located beneath-'and at oneside'oiE the chamber and having an inwardly extending projectionarranged beneath the chamber provided with a transversely extendinghydrocarbon linlet, a valve seat -in said passage and means at the endsof the passage for attaching a su ply of the reser-.` pivoted to ,thecasing beneath the pipe, of an armlocated at the bottom o' the reservoirand pivoted to the casing beneath the' chamber, a float connected totheone end ofthe arm, and-a valve head supported on the latter andcooperating with the seat in the inlet passage.

4; In a carbureter, the combination With a casing comprising a mixingchamber and a hydro-carbon reservoir located beneath and -at one side ofthe chamber and having a passage leading. into the reservoir'beneath thechamber and a valve seat in said passage, of an arm at the bottom ofthereservoir pivoted at one end beneath the chamber, a float conl nected tothe otherl end of stem carried on the arm vand cooperating with theinlet passage seat and aremovable at the bottom of the reservoir forminga gui e for the valve stem.

' 5. In a carbureter,'the combination with a casing having air inlet and-outlet passa es and a hydro-carbon inlet, having a -va 've seat, of larotary longitudinally movable member for adjusting the air passages anda valveyhead carried on saidmember and op-A eratedfby the longitudinalmovement thereof the arm, a valve 4 relatively to said valve seat.V

6. In-a carbureterJ the combination With a casing having air inlet andoutlet .passa es and a hydrocarbon inlet, having Ia valve seat, of asleeve threaded the 'casing and reyoluble thereinto-adjust the' airpassages, and a valve head on the sleeve coperating vwith said seatV andcarried relatively"theretoby the longitudinal movement of the-sleeve.

f .7 Ina oarbureter, the combination with "al casing having air. inlet.and outlet passages and a hydrocarbon inlet extending into the casingand having a valve seatpo a rotary sleeve in the casing, and a valvehead adjustable on the sleeve relatively to the valve seat, means forcansinor a relative longitudinal Isleeve during its rotary movement. l iHENRY L.
